Strap for Galactic 36 Automatic Stainless Steel / Pearl Diamond / Teju

The Breitling Galactic A3733012/A717/112Z/A16BA.1 has a lug width of 18mm. This measurement should be verified using a vernier calliper positioned between the lugs at the point of contact with the case. A 20mm strap is not compatible without modifications that would compromise both aesthetics and safety.

For the stainless steel Galactic 36 with its 36mm case, the most coherent choices are fine-grain Mississippiensis alligator for formal settings, vegetable-tanned calf leather for daily wear — it develops a rich patina over time — and shell cordovan for those seeking moisture resistance and depth of lustre. For sport or marine use, a nylon NATO or vulcanised rubber tropical strap are functional alternatives. The correct width is 18mm at the lug end.

Strap replacement requires a spring bar tool to remove the retaining bars from the lugs. On this model the lugs are narrow and curved, so a fine-tipped tool is recommended to avoid scratching the case. Remove the bar at the 6 o'clock side first, then the 12 o'clock side. Insert the new 18mm strap and refit the spring bars under pressure until you hear the double click of engagement.

Yes. Any 18mm strap with a straight or slightly curved end is compatible with the Breitling Galactic A3733012/A717/112Z/A16BA.1. Milanostraps.it offers a curated selection of handcrafted 18mm straps in various materials — alligator, calf leather, shell cordovan, rubber — fitted with a 316L stainless steel buckle or deployant clasp to maintain material coherence with the original case.

Longevity depends on the material and frequency of use. A vegetable-tanned calf leather strap worn daily typically lasts 18 to 24 months before showing significant wear at the holes. Alligator, thanks to the structure of its scales, generally lasts 2 to 3 years. Shell cordovan outlasts both due to the density of the leather. All Casati Milano straps carry an 18-month warranty against manufacturing defects.
